Description
Bestimmte Sorten von Kunstkautschuk, wie Mischpolymerisate von Butadien mit Acrylsäurenitril, zeichnen sich durch gute Ölbeständigkeit aus. Es ist auch bereits ein Vorschlag bekannt, durch Beigabe von weichmacherhaltigem Polyvinylchlorid oder vinylchloridhaltigen 1Tischpolymerisaten die Ozonfestigkeit derartiger synthetischer Kautschukmischungen zu erhöhen und die Brennbarkeit herabzusetzen. Die Erfindung beruht nun auf der Erkenntnis, daß das in neuzeitlichen Kautschukmischungen als Vulkanisationsaktiv ator übliche Zinkotyd in derartigen polyvinylchloridhaltigen ozonfesten Mischungen zu Zersetzungen des Polyvinylchlorids führt; das Zinkoxyd verbindet sich nämlich mit der von dem Polyvinylchlorid beim Vulkanisationsvorgang abgespaltenen Salzsäure zu Zinkchlorid, das einen äußerst schädlichen Einfluß auf das Polyvinylchlorid ausübt und als starker Elektrolyt die elektrischen Eigenschaften der Mischung stark verschlechtert.Certain types of synthetic rubber, such as copolymers of butadiene with acrylonitrile, are characterized by good oil resistance. It is also already known a proposal by adding plasticized polyvinyl chloride or vinyl chloride-containing copolymers, the ozone resistance of such synthetic Increase rubber compounds and reduce flammability. The invention is now based on the knowledge that in modern rubber compounds as Vulkanisationsaktiv ator common zinc oxide in such polyvinyl chloride ozone-resistant mixtures lead to decomposition of the polyvinyl chloride; the zinc oxide namely combines with that of the polyvinyl chloride during the vulcanization process split off hydrochloric acid to zinc chloride, which has an extremely harmful influence on the polyvinyl chloride exerts and as a strong electrolyte the electrical properties the mixture greatly deteriorated.
Gemäß der Erfindung wird daher bei der Herstellung ozonbeständiger, ölfester und schwerbrennbarer Vulkanisate aus 'Mischungen von künstlichem Kautschuk und weichmacherhaltigem Polvvinylchlorid oder Vinylchlorid enthaltenden Mischpolymerisaten an Stelle von Zinkoxyd als Vulkanisationsaktivator Bleioxyd verwendet. Denn das aus diesem sich bildende Bleichlorid übt keine zersetzende Wirkung auf das Polyv iny lchlorid aus. Infolge seiner Wasserunlöslichkeit verschlechtert es auch nicht die elektrischen Eigenschaften der Mischung.According to the invention is therefore in the production of ozone-resistant, Oil-resistant and flame-retardant vulcanizates made from mixtures of synthetic rubber and copolymers containing plasticized polyvinyl chloride or vinyl chloride lead oxide is used instead of zinc oxide as vulcanization activator. Because that lead chloride formed from this has no decomposing effect on the poly inyl chloride. It also does not deteriorate due to its insolubility in water the electrical properties of the mixture.
Nachstehend wird ein Beispiel für eine Mischung gemäß der Erfindung .gegeben, ohne daß die Erfindung hierauf beschränkt wäre. Die Mischungsverhältnisse können hiervon in weiten Grenzen abweichen, und es können gegebenenfalls auch noch andere Füllstoffe vorgesehen werden. ioo Teile eines künstlichen Kautschuks. insbesondere eines -Mischpolymerisates von Butadien mit Acrylsäurenitril, 6,9 Teile Poly vinylchlorid, 5o Teile eines üblichen Weichmachers für Polvvinvlchlorid, z. B. Tikresylphosphat, 1,5 Teile Schwefel, 2 Teile Vulkanisationsbeschleuniger, z. B. Vulkazit D. 1I., 2 Teile eines üblichen Alterungsschutzmittels, z. B. Aldolpulver, i Teil Stearinsäure, 2o Teile Bleiglätte.The following is an example of a mixture according to the invention .Given without the invention being restricted thereto. The mixing ratios can deviate from this within wide limits, and it may also be possible other fillers can be provided. 100 parts of an artificial rubber. in particular a copolymer of butadiene with acrylonitrile, 6.9 parts of poly vinyl chloride, 50 parts of a conventional plasticizer for polyvinyl chloride, e.g. B. ticresyl phosphate, 1.5 parts sulfur, 2 parts vulcanization accelerator, e.g. B. Vulkazit D. 1I., 2 parts of a conventional anti-aging agent, e.g. B. aldol powder, i part stearic acid, 2o parts of black lead.
Bei der Herstellung einer solchen Mischung werden zunächst das Polyvinylchlorid und der Weichmacher miteinander vermengt, worauf die Masse bei i2oL C mit dem künstlichen Kautschuk homogen verknetet wird. Anschließend werden dann die übrigen Mischungsbestandteile in üblicher Weise eingewalzt.In the production of such a mixture, the polyvinyl chloride is used first and the plasticizer mixed together, whereupon the mass at i2oL C with the artificial Rubber is kneaded homogeneously. Then the remaining components of the mixture are then used rolled in in the usual way.
Die Mischung gemäß der Erfindung ist für alle Zwecke verwendbar, bei denen höchste Anforderungen an Ölbeständigkeit und Ozonfestigkeit sowie Schwerbrennbarkeit gestellt werden. Beispielsweise ist die Mischung mit Vorteil für die Herstellung von Mänteln für bewegliche elektrische Kabel und Leitungen oder von Deckschichten für die Isolierung von Hochspannungsleitungen sowie für Formartikel an Hochspannungsgeräten u. dgl. verwendbar.The mixture according to the invention can be used for all purposes which meet the highest requirements in terms of oil resistance and ozone resistance as well as flame resistance be asked. For example, the mixture is advantageous for manufacturing of sheaths for movable electrical cables and lines or of cover layers for the insulation of high-voltage lines as well as for molded articles on high-voltage devices and the like can be used.
In der Zeichnung sind einige Anwendungsbeispiele einer Mischung gemäß der Erfindung dargestellt.In the drawing are some application examples of a mixture according to of the invention shown.
Fig. i zeigt ein bewegliches elektrisches Kabel, dessen Leiter i mit einer Isolierung aus natürlichem oderkünstlichem Kautschuk versehen sind und das einen Mantel 3 aus einem Kautschuk gemäß der Erfindung besitzt. Ein solches Kabel eignet sich wegen der Unbrennbarkeit des Mantels besonders zur Verwendung im Bergbau unter Tage.Fig. I shows a movable electrical cable, the conductor i with an insulation made of natural or synthetic rubber and that has a jacket 3 made of a rubber according to the invention. Such a cable Because of the incombustibility of the jacket, it is particularly suitable for use in mining underground.
Fig. 2 zeigt eine Hochspannungszündleitung. deren Leiter 4. eine Isolierung 5 aus einem künstlichen Kautschuk mit einer darüber angebrachten Deckschicht 6 aus einer ozonfesten Gummimischung gemäß der Erfindung und darüber eine Faserstoffbeflechtung 7 besitzt.Fig. 2 shows a high voltage ignition line. their conductors 4. an insulation 5 made of an artificial rubber with a cover layer 6 applied over it an ozone-resistant rubber mixture according to the invention and above it a fiber braid 7 owns.
